These 1300mAh USB Cell batteries aren’t your the typical batteries that you would pick up at the gas station. Instead, you can plug these directly into your computer’s USB ports in order to give them a charge.
Unfortunately it will take you around 5 hours just to get these things up to a 90% charge, which seems a little long to me. Get yourself a USB hub and you can have yourself a nice little charging station.
UK Price: £12.99
